Summary
This earth dam stands at a height of 55 feet and spans a length of 1150 feet, with a storage capacity of 6455 acre-feet and a surface area of 93 acres. While the dam is designated as having a high hazard potential, its condition is assessed as fair and it is inspected biennially to ensure its safety.
Managed by a private owner, Rabon Creek WCD Dam 20 is regulated by the SC DHEC and falls under the jurisdiction of the state of South Carolina. Despite being a privately owned structure, it plays a crucial role in protecting the surrounding area from potential flooding events. The dam's uncontrolled spillway and outlet gates are designed to handle moderate risk levels, with emergency action plans in place to address any potential hazards that may arise.
For water resource and climate enthusiasts, Rabon Creek WCD Dam 20 offers a fascinating case study in the intersection of infrastructure, regulation, and environmental stewardship. Its design and construction by the USDA NRCS, combined with its ongoing management and inspection protocols, highlight the importance of proactive measures in safeguarding communities against the impacts of extreme weather events. As climate change continues to pose challenges to water resource management, structures like Rabon Creek WCD Dam 20 stand as crucial elements in mitigating flood risks and promoting resilience in the face of a changing climate.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
